Why does boot time matter? Is something wrong with the sleep mode in your laptop? > tho@phobos:/usr/local/src/sbcl$ uptime 11:31:50 up 250 days, 21:10, 1 user, load average: 0.60, 0.37, 0.40

Is there something wrong with the sleep mode on your desktop?

I can't believe you're not mentioning the super high power draw of 8k monitors. It's so bad that i'm not even considering getting one.

The power is not so bad, especially compared to the graphics cards you would want to use (and I use my GPU as a tow warmer). Samsung 8k specifically comes with low power presets which are probably usable in this scenario. Of course with so many more pixels in 8k than in 4k there is need for more power but the EU regulation allows selling them if they also support an eco mode.

> I am old enough to recall 100W as the typical single light bulb

I'm regularly in a museum where they showcase some of the 1800s/1900s wares of households in my area. One is a kerosene/gasoline powered clothes iron. Just because something was one common doesn't mean it was good.

> I still use an electric tea kettle that touches the multi kW range daily

How many hours a day is your tea kettle actually using multi-kW? The more useful comparison is how many kWh/day are these appliances using.

Author here, ask me anything! Apart from programming, one of the motivations for getting the 8K display is to look at lidar point clouds. For example the desktop background in my post is a lidar map of Bernal Hill in San Francisco, which I've here downsampled to only 13006 x 7991 px for your convenience [1]. Admittedly, when I bought it at first, I didn't realize there would be so many random issues, as manufacturers…

In case you're wondering whether this works on a Mac, like I did, I found this source[0]. In short, you need an M2 Pro or better, and may need to edit a plist file to get it to work. [0] https://scottstuff.net/posts/2023/10/10/samsung-8k/

Here's my central question: In the early 4k era, whenever I saw a TV used as a monitor, the eye strain was high. It was too bright, too contrasty, and generally, the picture was not great for using for things like programming. In addition, many TVs would do not-so-great things to the picture, the worst being digitally sharpening the image (which resulted in e.g. a halo effect around small text). This might not bother…

Fortunately, modern TVs can disable the sharpening and contrast/saturation enhancements. Since I do a lot of photography and image processing, I am also extremely sensitive to oversharpened halos, so I was a bit worried about that at first --- but fortunately, that is 100% nonexistent once I applied the appropriate settings on my Samsung QN800A. See pics: [1] [2]

I also detest the miniled HDR that they have going on, which can cause bright things to glow, so I disabled that. Unfortunately my QN800A still have a bit of "full screen HDR", namely, that the whole screen may uniformly dim if it detects that the scene is dark. This means that sometimes when you have a black screen with a single cursor on it, it gets dark, and it becomes hard to see the cursor. This doesn't affect normal usage though, when the screen is at a constant brightness.

I've recently swapped out my dumb TV with a smart TV. The choice to go smart after clinging on to my dumb TV + old-school Chromecast was only motivated by advances in display tech. In retrospect the smart TV is a considerably worse experience UX-wise than the dumb TV + Chromecast. The built-in Chromecast in the new TV requires the TV to be logged into accounts for all the "apps" that the TV has. I can no longer just…

As far as I know the lesson here is, never, ever, connect your TV to the Internet.

I did in fact buy a knock-off from ebay battery, but it kept it kept it's charge for hilariously little time. Had to run it of mains power permanently (ran it as a little server for a while).

Don't know your exact timing but I run basically on Dells Latitude laptops for past 2 decades. Since its just for travel and not my primary workhorse, I buy used corporate ones for pittance (cca 300$ for models worth 1500 few years before), and swap battery myself for another original OEM one, they cost less than 100$ from original manufacturer. Its just 2-3 philips screws and 1 cable, anybody can do it. They last ju…

This was mid 2010s and the laptop has long since bit the dust. IIRC this was a Dell Studio 15, but I recall checking eBay for old new stock with no luck, but it doesn't surprise me that the Dell Latitudes have lots of stock floating around ebay.

On a LG tv you can disable this with buying a ‘service remote’ from amazon and acces a special menu. ( look for TPC or GSR settings ). I don’t know about samsung though.

I've tried all sorts of configurations and I settled on two 27" 5K monitors (in HiDPI mode) on a VESA mount so they can easily be rotated for different use cases. The biggest selling point was text clarity. I really like using my code editor in vertical mode.

My previous setup was a 34" curved ultrawide and I didn't like it. Primarily due to the poor text quality and generally feeling it encouraged too much distraction.

I like being able to have very separate concerns per-display -- code editor on one display and browser on the other, and then I use virtual desktops on each one where needed.

I've been using TVs as my monitor for probably 10 years now. I've been on my current Vizio 50" 4k TV since before covid. I think I bought it for $280? I do everything from programming, watching or up-scaling videos, and playing FPS games on it. My only issue has been vsync related tearing in certain games like God of War for PC even though I have vysnc settings on, but other than that, no problems. I do well in fast-paced Fortnite games, so latency hasn't been an issue either. I'm near-sighted and hate wearing glasses, so having the larger fonts has been a blessing also.

Fair enough. Though I didnt live during kerosene times. My tea kettle uses 0.06kWh per session. So one to two weeks of tea for me to reach the energy of a day on such a monitor (see other comment on best guesses on energy use of this monitor). On the other hand, a typical pasta recipe on an electric stove would be 2kWh, so several days of use of such a monitor.
